Local Manifest V3 preflight scanner

Chrome Extension Rejection Checker

Scan a Chrome extension ZIP locally before Chrome Web Store submission. The tool checks package structure, manifest references, remote hosted code signals, dynamic code execution, CSP, permissions, icons, and privacy review reminders without uploading source code.

What makes this tool review-ready

• Your ZIP is read in the browser and is not uploaded by the tool.
• The report is a static preflight check, not an official Chrome Web Store approval guarantee.
• Use the final production ZIP because Chrome Web Store reviews the submitted package.
